What is a Domain Name?
A domain name uniquely identifies a website and it's address. Typing a domain name (also called a URL) into
the upper box of your browser allows you to visit that site.
One unique domain name can be used as a company's web address and for its email addresses.

Domains are much more than just names typed into a web browser. Your domain name is how the world will think of you and your business. It's part of your brand and your marketing plan. You can have multiple domains that each relate to some aspect of your business. A domain can be easy to remember and help establish you on the web.

A domain name is a unique name which identifies a specific internet resource such as a website.
It is an identification that defines a realm of administrative
authority or control on the Internet. Domain names are formed by rules of the Domain Name System (DNS).
Any name registered in the DNS is a domain name. Domain names are used in various networking contexts and
application-specific naming
and addressing purposes. In general, a domain name represents an Internet Protocol (IP)
resource, such as a personal computer used to access the Internet, a server computer
hosting a web site, or the web site itself or any other service communicated via the Internet.
The number of active domains has now reached 300 million. Now the wave of social networks affect how people register
domains. Facebook has 1.5 billion user accounts and we are seeing a trend where people are using domain names to
point into social networks for marketing purposes.

Domain names are organized into subordinate levels (subdomains) of the DNS root domain,
which is nameless. The first-level set of domain names are the top-level domains (TLDs),
including the generic top-level domains (gTLDs), such as the prominent domains com, info,
net, edu, and org, and the country code top-level domains (ccTLDs). Below these top-level
domains in the DNS hierarchy are the second-level and third-level domain names that are
typically open for reservation by end-users who wish to connect local area networks to the Internet,
create other publicly accessible Internet resources or run web sites.
The registration of domain names are administered by domain name registrars.

Anatomy Of A Domain Name
You most often see domains listed as www.empathize.com.
A domain consists of two main parts. Let's use www.CatchyDomainNames.com as an example:
The first part, "buydomains"
This is the unique part of the name. It represents your company or brand name.
It is how you will be branded and known on the web.
The last part is called the extension
In our example it is ".com." Other popular extensions are .net, and .org.
Many people will automatically type in .com after any domain.
Securing the other extensions can make sense for many people,
as they help protect your brand throughout the web.
What Will My Email Address Look Like?
One of the most popular reasons to have a domain name is to have
personalized email, either for your business or for personal reasons.

An email is a unique address, followed by your domain name,
such as "sales@yourcompany.com" or "help@catchydomainnames.com."
You can often create multiple email addresses for each domain you own,
so that each member of your company has their own address.
